Ошибка в открытии проекта в Sony Vegas 9

Сделал видео (убил уйму времени) , сохранил как проект, открываю: выдаёт ошибку:

"An error occurred while loading the project fil Unititled.veg

The reason for the error could not be determined.

Media file E:\Documents and Settings\Admin\Мои документы\Untitled.veg has changed enough that the media stream properties from the project file could not be applied. Default media stream properties were used.

Как это обойти?
